TECHNICAL FIELD

The present teachings are generally directed to dermal patch systems that can be employed to collect a physiological sample from a subject.

BACKGROUND

Biomarkers are increasingly employed for diagnosis of various disease conditions as well as for assessing treatment protocols. In many cases, it is important to monitor the level of a biomarker over time (e.g., to assess the progression of a disease). The temporal monitoring of biomarkers via conventional techniques includes drawing a physiological fluid sample from a subject. These techniques may be cumbersome and painful to the subject. For example, the invasive nature of drawing a blood sample from a subject can cause discomfort and may lead to less cooperation from a subject, especially children, rendering multiple measurements of a target analyte difficult.

Some recently developed devices allow for continuous monitoring of a target analyte (e.g., glucose monitors). Unfortunately, these devices typically suffer from several shortcomings, such as low sensitivity and/or specificity.

DETAILED DESCRIPTION

The present disclosure generally relates to a dermal patch system (which may also be referred to as a “dermal patch”) that may be utilized to collect and optionally store a physiological sample.

In various embodiments, a dermal patch system may be used to collect a physiological sample and the collected sample may then be stored on a sample collection pad of the dermal patch system. Dermal patch systems disclosed herein may allow for the collection and analysis of a physiological sample in a variety of environments (e.g., at home, in the field, in a medical facility, etc.).

The term “about,” as used herein, denotes a deviation of at most 10% relative to a numerical value. For example, about 100 μm means in the range of 90 μm-110 μm.

The term “substantially,” as used herein, refers to a deviation, if any, of at most 10% from a complete state and/or condition.

The term “subject” as used herein refers to a human subject or an animal subject (i.e., chicken, pig, cattle, dog, cat, etc.).

The term “transparent,” as used herein, indicates that light can substantially pass through an object (e.g., a window) to allow visualization of a material disposed behind the object. For example, in some embodiments, a transparent object allows the passage of at least 70%, or at least 80%, or at least 90% of visible light therethrough.

The term “needle” as used herein, refers to a component with a pointed tip that is configured to pierce an outer surface of an element (e.g., skin of a subject) to provide a passageway through which a physiological fluid can be extracted.

The term “vacuum,” as used herein, refers to a pressure less than atmospheric pressure and more particularly to a pressure that can facilitate the movement of a fluid (e.g., a physiological sample) within a dermal patch system according to various embodiments.

The present disclosure generally relates to a device, which is herein also referred to as a dermal patch or a dermal patch system, for collecting a physiological sample (e.g., bodily fluids such as blood, interstitial fluids, etc.) from a subject. In some embodiments discussed below, such a dermal patch system can include a cartridge that can be affixed to a subject's skin (e.g., via an adhesive layer) and a separate lancet that can be engaged with the cartridge to puncture the skin, thereby providing a passageway for extracting the physiological sample. As discussed in more detail below, the lancet can include a housing in which at least one needle that is configured for puncturing the skin is disposed. The lancet can further include a mechanism that can be transitioned between at least two states, wherein in one state (herein referred to as a locked state), the mechanism retains the needle(s) within the lancet in an undeployed position when the lancet is not engaged with the cartridge and in another state (herein referred to as a released state), the mechanism allows the needle(s) to be deployed for puncturing the skin in response to engagement of the lancet with the cartridge. In other words, the engagement of the lancet with the cartridge transitions the mechanism from the locked state to the released state, where in the released state, the mechanism allows the needle(s) to be deployed for puncturing the skin. For example, in some embodiments, the mechanism can include an upper locking portion that can retain an upper spring that is coupled to a needle platform (to which a needle is mounted) in a compressed state, thereby preventing the needle(s) from transitioning into a deployed position. Further, the mechanism can include an upper interference member that prevents the movement of the needle platform when the mechanism is in the locked state.

The engagement of the lancet with the cartridge's housing results in an automatic transition of the mechanism from the locked state to the released state, which transitions the needle(s) into a deployed position in which the needle(s) extends beyond the lancet's housing and the cartridge housing to puncture the subject's skin. In some embodiments, the engagement of the lancet with the cartridge causes the upper locking member to release the needle platform, which in turn allows the upper spring to decompress and thus push down the needle platform thereby deploying the needle(s). In some embodiments, the mechanism can further include a lower interference member that restricts the downward movement of the needle platform, when the needle platform is released. In this manner the extent of the penetration of the needle(s) into the skin can be controlled. In certain embodiments, the mechanism can also include a lower locking member that retains a lower spring in a compressed state. The downward movement of the needle platform can cause the release of the lower locking member to allow the lower spring to decompress and exert a force on the needle platform to cause the retraction of the needle(s) into the lancet housing.

In this manner, the lancet remains safe before it is engaged with the cartridge as the lancet is not capable of deploying the needle(s) when the lancet is not engaged with the cartridge. Furthermore, in this manner, the lancet remains safe after drawing a physiological sample as the needle(s) automatically retracts back into the lancet's housing after being deployed.

Referring now to FIG. 1 , a dermal patch system 10 is shown in accordance with an exemplary embodiment. The dermal patch system 10 includes a cartridge 12 that can be affixed to a subject's skin (e.g., via an adhesive layer disposed on a bottom surface of the cartridge 12) and a lancet 100. As will be discussed in further detail herein, the lancet 100 can be activated to deploy a needle disposed within the lancet 100 to puncture the subject's skin thereby drawing a physiological sample from the subject.

Referring to FIGS. 2-6 , the lancet 100 is shown in accordance with an exemplary embodiment. The lancet 100 includes a housing 102 in which various components of the lancet are disposed and a cap 104 that is coupled to the housing 102. The lancet 100 can further include an inner sleeve 106 within the housing 102 and a needle frame 108 that is disposed within the inner sleeve 106 and onto which a needle(s) 110 is mounted. While the needle frame 108 is depicted as supporting one needle(s) 110 in other embodiments, the needle frame 108 may support multiple needles 110 (e.g., 2, 3, 4, etc.). The lancet 100 also can include an injection spring 112 and a refraction spring 114 that move a needle of the lancet between various positions.

With particular reference to FIGS. 3A and 3B, the housing 102 includes a side wall 116 and a bottom wall 118. The side wall 116 includes an outer surface 116 a and an opposed inner surface 116 b. The bottom wall 118 includes an outer surface 118 a and an opposed inner surface 118 b. The side wall 116 extends vertically from the bottom wall 118. The side wall 116 has a generally cylindrical shape and the bottom wall 118 is generally circular in shape and is concentric relative to a longitudinal axis of the generally cylindrical side wall and covers a lower opening formed by the generally cylindrical side wall. The inner surface 116 b of the side wall 116 and the inner surface 118 b of the bottom wall 118 define an inner volume 120.

The outer surface 116 a defines a notch 122 that extends circumferentially around the outer surface 116 a of the side wall 116. The housing 102 further includes a rim 124 that extends circumferentially around the outer surface 116 a of the side wall 116. The inner surface 116 b defines a first and second column 126 that extend vertically from the inner surface 118 b of the bottom wall 118. The columns 126 includes an inner surface 126 a and a top surface 126 b. The inner surface 126 a extends vertically between the inner surface 118 b of the bottom wall 118 and the top surface 126 b. The top surface 126 b extends longitudinally between the inner surface 116 b of the side wall 116 and the inner surface 126 a.

As will be discussed in further detail herein, before the lancet 100 is inserted into the cartridge 12, the columns 126 retain the needle(s) 110 of the lancet 100 in an undeployed position.

The bottom wall 118 defines an aperture 128 that extends through the bottom wall 118. Stated another way, the aperture 128 extends between the outer surface 118 a and the inner surface 118 b of the bottom wall 118. As will be discussed in further detail herein, when the lancet is activated via engagement with the cartridge 12, the needle(s) of the lancet 100 is activated to extend through the aperture 128 and puncture the subject's skin thereby providing a passageway through which a physiological sample can be drawn from a subject.

With particular reference to FIGS. 4A and 4B the cap 104 includes a top wall 130 with an outer surface 130 a and an opposed inner surface 130 b. The cap 104 also includes a side wall 132 with an outer surface 132 a and an opposed inner surface 132 b. The top wall 130 extends longitudinally from and perpendicular to the side wall 132. The side wall 132 extends vertically from and perpendicular to the top wall 130. The top wall 130 and the side wall 132 are generally circular in shape and are concentric with one another. The cap 104 also includes an inner cylinder 134 with an outer surface 134 a and an opposed outer surface 134 b. The inner cylinder 134 extends vertically from and perpendicular to the top wall 130. The inner cylinder 134 is concentric with the top wall 130 and the side wall 132.

When the cap 104 is coupled to the housing 102 the side wall 132 extends into the inner volume 120 of the housing 102 and at least a portion of the side wall 132 contacts the inner surface 116 b of the side wall 116 such that the cap 104 couples to the housing 102 via an interference fit.

As depicted in FIG. 5 , the inner sleeve 106 includes a side wall 136 and a bottom wall 138. The side wall 136 includes an outer surface 136 a and an opposed inner surface 136 b. The bottom wall 138 includes an outer surface 138 a and an opposed inner surface 138 b. The side wall 136 extends vertically from the bottom wall 138. The side wall 136 and the bottom wall 138 are generally circular in shape and are concentric with one another. The inner surface 136 b of the side wall 136 and the inner surface 138 b of the bottom wall 138 define an inner volume 140. The inner surface 136 b defines a plurality of columns 142 each of which extends vertically from and perpendicular to the inner surface 138 b of the bottom wall 138. As will be discussed in further detail herein, when the needle frame 108 is in a deployed position, a portion of the needle frame 108 rests upon the columns 142.

The inner sleeve 106 further includes a plurality of ledges 144 that extend circumferentially about the side wall 136. Each ledge 144 includes a top surface 144 a, an opposed bottom surface 144 b and an outer surface 144 c that extends between the top surface 144 a and the bottom surface 144 b. The inner sleeve 106 also includes a plurality of locking members 146 that extend from the inner surface 136 b of the side wall 136. As will be discussed in further detail herein, the proximal end of the locking members 146 retains the retraction spring 114 in a compressed state in absence of engagement between the lancet 100 and the cartridge 12. The side wall 136 further defines a plurality of openings 148 that extend through the side wall 136. Stated another way, the openings 148 extend between the outer surface 136 a and the inner surface 136 b of the side wall 136. Each of the openings 148 is aligned with a proximal end of a locking member 146 to allow the proximal end of a locking member 146 to extend therethrough.

The bottom wall 138 defines an aperture 150 that extends through the bottom wall 138. Stated another way, the aperture 150 extends between the outer surface 138 a and the inner surface 138 b of the bottom wall 138. The aperture 150 is concentric with the aperture 128 of the housing 102. As will be discussed in further detail herein, when in a deployed position, the needle(s) 110 of the lancet 100 extends through the aperture 150 of the inner sleeve 106 as well as the aperture 128 of the housing 102.

As depicted in FIG. 6 , the needle frame 108 includes a first cylinder 152 and a second cylinder 154 disposed vertically above the second cylinder 154. The first cylinder 152 includes a bottom surface 152 a and an outer surface 152 b.

The third cylinder 156 includes an outer surface 156 a and a top surface 156 b. Similarly, the protrusion 158 includes an outer surface 158 a and a top surface 158 b.

The bottom surface 152 a of the first cylinder 152 extends circumferentially about the outer surface 152 b of the first cylinder. The outer surface 152 b of the first cylinder 152 extends vertically between the bottom surface 152 a of the first cylinder 152 and the bottom surface 154 a of the second cylinder 154. The bottom surface 154 a of the second cylinder 154 extends at an angle longitudinally between the outer surface 152 b of the first cylinder and the outer surface 154 b of the second cylinder 154. The outer surface 154 b extends vertically between the bottom surface 154 a and the top surface 154 c of the second cylinder 154. The top surface 154 c of the second cylinder 154 extends longitudinally between the outer surface 154 b of the second cylinder and the outer surface 156 a of the third cylinder 156. The outer surface 156 a extends vertically between the top surface 154 c of the second cylinder and the top surface 156 b of the third cylinder. The top surface 156 b of the third cylinder extends longitudinally between the outer surface 156 a of the third cylinder 156 and the outer surface 158 a of the protrusion 158. The outer surface 158 a extends vertically between the top surface 156 b of the third cylinder and the top surface 158 b of the protrusion 158. The top surface 158 b of the protrusion 158 extends across a proximal end of the outer surface 158 a.

The injection spring 112 extends vertically between the cap 104 and the needle frame 108. More specifically, a distal end of the injection spring 112 contacts the inner surface 130 b of the top wall 130 and a proximal end of the injection spring 112 contacts the top surface 154 c of the second cylinder 154. The distal end of the injection spring 112 extends circumferentially around the outer surface 134 a of the inner cylinder 134. The proximal end of the injection spring 112 extends circumferentially around the third cylinder 156 and around the protrusion 158.

The needle frame 108 supports the needle(s) 110. In some embodiments, the needle(S) 110 is molded into the first cylinder 152 or is attached to the bottom surface 152 a of the first cylinder 152 (e.g., via an adhesive).

Referring to FIG. 7 , the cartridge 12 is shown in accordance with an exemplary embodiment. As will be discussed in further detail herein, the cartridge 12 is formed of a plurality of layers of suitable materials including, but not limited to, polymeric materials (e.g., polyolefins, polyethylene terephthalate (PET), polyurethanes, polynorbornenes, polyethers, polyacrylates, polyamides (Polyether block amide also referred to as Pebax®), polysiloxanes, polyether amides, polyether esters, trans-polyisoprenes, polymethyl methacrylates (PMMA), cross-linked trans-polyoctylenes, cross-linked polyethylenes, cross-linked polyisoprenes, cross-linked polycyclooctenes, inorganic-organic hybrid polymers, co-polymer blends with polyethylene and Kraton®, styrene-butadiene co-polymers, urethane-butadiene co-polymers, polycaprolactone or oligo caprolactone co-polymers, polylactic acid (PLLA) or polylactide (PL/DLA) co-polymers, PLLA-polyglycolic acid (PGA) co-polymers, photocross linkable polymers, etc.). In some embodiments, all or a portion of each material layer may be formed of poly(dimethylsiloxane) (PDMS) to allow visibility of components disposed within the cartridge 12. While the various layers of material that form the cartridge 12 are said to be layers of polymeric material, it is understood that the layers of material that form the cartridge 12 may be formed of any suitable material (e.g., metal, metal alloy, etc.). As will be discussed in further detail herein, the layers can be stacked and coupled to one another to form the cartridge 12. In some embodiments, the layers of the cartridge 12 may be formed of aluminum or other suitable metals. In certain embodiments, the layers of the cartridge 12 may be formed of a polymeric coated with aluminum film or another suitable metal film.

The cartridge 12 includes an adhesive layer 200, a bottom layer 300 of polymeric material, a middle layer 400 of polymeric material, a top layer 500 of polymeric material, and a moveable vacuum pin 600 that is disposed between the middle layer 400 and the top layer 500. The cartridge 12 also includes a protective liner 14 (e.g., formed of paper) that covers the adhesive layer 200. The protective liner 14 protects the adhesive layer 200 before the cartridge 12 is attached to the skin of a subject.

As depicted in FIG. 8 , the adhesive layer 200 includes a top surface 202 and an opposed bottom surface 204. The adhesive layer 200 also includes a sample well opening 206 and an air pathway 208 each of which extends through the adhesive layer 200. That is, the sample well opening 206 and the air pathway 208 extend between the top surface 202 and the bottom surface 204.

The bottom layer 300 (FIG. 9 ) can have a thickness in a range of about 0.4 mm to about 0.6 mm (e.g., 0.5 mm) and includes a top surface 302 and an opposed bottom surface 304. The bottom layer 300 also includes a first sample well opening 306 that is connected to a sample channel 308. The bottom layer 300 further includes a T-shaped vacuum channel 310 that is separate from the first sample well opening 306 and the sample channel 308. The first sample well opening 306, the sample channel 308, and the vacuum channel 310 extend through the bottom layer 300. That is, the first sample well opening 306, the sample channel 308, and the vacuum channel 310 extend between the top surface 302 and the bottom surface 304 of the bottom layer 300.

By way of example, the middle layer 400 (FIG. 10 ) can have a thickness in a range of about 0.4 mm to about 0.6 mm (e.g., 0.5 mm) and includes a top surface 402 and an opposed bottom surface 404. The middle layer further includes a sample well opening 406 that is substantially similar in shape and dimension to the first sample well opening 306 of the bottom layer 300. The middle layer 400 also includes a vacuum aperture 408, a first vacuum via 410 and a second vacuum via 412. The first vacuum via 410 and the second vacuum via 412 are substantially similar in shape and dimension. Furthermore, the middle layer 400 includes a first sample via 414 and a second sample via 416 that are substantially similar in shape and dimension. The sample well opening 406, the vacuum aperture 408, the first vacuum via 410, the second vacuum via 412, the first sample via 414, and the second sample via 416 extend through the middle layer 400. That is, the sample well opening 406, the vacuum aperture 408, the first vacuum via 410, the second vacuum via 412, the first sample via 414, and the second sample via 416 extend between the top surface 402 and the bottom surface 404 of the middle layer 400. The sample via 414 and the second sample via 416 may be positioned elsewhere on the middle layer 400 (e.g., closer to a center of the middle layer 400).

By way of example, the top layer 500 (FIGS. 11 and 12 ) can have a thickness in a range of about 0.4 mm to about 0.7 mm (e.g., 0.45 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, etc.) and includes a top surface 502 and an opposed bottom surface 504. The top layer 500 includes a first sample collection pad opening 506 and a second sample collection pad opening 508 that are substantially similar in shape and dimension. The top layer 500 also includes a circular needle aperture 510. The first sample collection pad opening 506, the second sample collection pad opening 508, and the needle aperture 510 extend through the top layer 500. That is, the first sample collection pad opening 506, the second sample collection pad opening 508, and the needle aperture 510 extend between the top surface 502 and the bottom surface 504 of the top layer 500. The top layer 500 further includes a circular extension 512 that extends vertically from and perpendicular to the top surface 502. The circular extension 512 is concentric with and extends around the needle aperture 510. The top layer 500 also includes a first C-shaped extension 514 and a second C-shaped extension 516 both of which extend vertically from and perpendicular to the top surface 502. The first C-shaped extension 514 and the second C-shaped extension 516 are concentric with and extend partially around the circular extension 512. Furthermore, the top layer 500 defines a groove 518 and includes a raised surface 520. As will be discussed in further detail herein, the groove 518 aids in retaining the vacuum pin 600 within the cartridge 12.

With reference to FIG. 13 , when the cartridge 12 is assembled, the top surface 202 of the adhesive layer 200 is attached to the bottom surface 304 of the bottom layer 300 such that the sample well opening 206 of the adhesive layer 200 aligns with the sample well opening 306 of the bottom layer 300. Furthermore, when the adhesive layer 200 is attached to the bottom layer 300, the adhesive layer 200 covers the sample channel 308 and covers a majority of the vacuum channel 310. The air pathway 208 aligns with a portion of the vacuum channel 310 to provide an air passageway through the adhesive layer 200 and the bottom layer 300. The air pathway 208 provides airflow and supports the drying of the collection pads before and after collecting the physiological sample.

As depicted in FIG. 14 , when the cartridge 12 is assembled, the top surface 302 of the bottom layer 300 is attached to the bottom surface 404 of the middle layer 400 such that the sample well opening 306 of the bottom layer 300 and the sample well opening 406 of the middle layer 400 align. Together, the sample well opening 306 and the sample well opening 406 form a sample well of the cartridge 12. In some embodiments, the sample well is configured to retain about 60 μl to about 100 μl. Furthermore, when the bottom layer 300 is attached to the middle layer 400, the middle layer covers a majority of the sample channel 308 and the vacuum channel 310. The vacuum aperture 408 aligns with an end of the shaped vacuum channel 310 and the first vacuum via 410 and the second vacuum via 412 align with opposing sides of an end of vacuum channel 310 such that the vacuum aperture 408, the vacuum via 410 and the second vacuum via 412 provide passage through the middle layer 400 to the vacuum channel 310. That is, the vacuum aperture 408, the vacuum via 410 and the second vacuum via 412 are in open communication with the vacuum channel 310. The first sample via 414 and the second sample via 416 align with opposing ends of the sample channel 308 such that first sample via 414 and the second sample via 416 provide passageway through the middle layer 400 to the sample channel 308. That is, the first sample via 414 and the second sample via 416 are in open communication with the sample channel 308. The sample channel 308 and the first sample via 414 form a first sample pathway and the sample channel 308 and the second sample via 416 form a second sample pathway.

With reference to FIGS. 15 and 16 , when the cartridge 12 is assembled, the top surface 402 of the middle layer 400 is attached to the bottom surface 504 of the top layer 500 such that the needle aperture 510 aligns with the sample well opening 406. That is, the needle aperture 510 aligns with the sample well to provide a passageway through the cartridge 12. Also, when assembled, the first vacuum via 410 aligns with a corner of the first sample collection pad opening 506 and the second vacuum via 412 aligns with a corner of the second sample collection pad opening 508. Furthermore, the first sample via 414 aligns with a center of the first sample collection pad opening 506 and the second sample via 416 aligns with a center of the second sample collection pad opening 508. The first sample collection pad opening 506 provides passageway through the top layer 500 to the first vacuum via 410 and the first sample via 414. That is, the first sample collection pad opening 506 is in open communication with the first vacuum via 410 and the first sample via 414. The second sample collection pad opening 508 provides a passageway through the top layer 500 to the second vacuum via 412 and the second sample via 416. That is, the second sample collection pad opening 508 is in open communication with the second vacuum via 412 and the second sample via 416. When assembled, the groove 518 of the top layer 500 is disposed vertically above the vacuum aperture 408 such the groove 518 is in open communication with the vacuum aperture 408. The top surface 402 of the middle layer 400 and the groove 518 of the top layer 500 define a recess (also referred to herein as a “vacuum pin receptacle”) that is shaped and dimensioned to accept at least a portion of the vacuum pin 600. Furthermore, the raised surface 520 and the top surface 402 define a cavity. In some embodiments, the cavity may be about 800 mm³and may retain about 1 g (e.g., 0.5 g-1.5 g) of desiccant (e.g., Silica Gel).

When the cartridge 12 is assembled, the vacuum aperture 408 is in open communication with the first vacuum via 410 and the second vacuum via 412 via the vacuum channel 310. The vacuum channel 310, the vacuum aperture 408, and the first vacuum via 410 form a first vacuum pathway and the vacuum channel 310, the vacuum aperture 408, and the vacuum channel 310, the vacuum aperture 408, and the second vacuum via 412 form a second vacuum pathway. Furthermore, the first vacuum pathway is in communication with the first sample pathway via the first sample collection pad opening 506 and the second vacuum pathway is in communication with the second sample pathway via the second sample collection pad opening 508.

The bottom layer 300, the middle layer 400, and the top layer 500 may be affixed to one another by ultrasonic welding, laser welding, or pressure sensitive adhesive. In some embodiments, bottom layer 300, the middle layer 400, and the top layer 500 may be formed by die cutting, injection molding, vacuum forming, or pressure molding.

In some embodiments, the bottom layer 300, the middle layer 400, and the top layer 500 may be formed via die cutting or vacuum forming (or other methods) that result in a large reel or sheet of each layer. These reels may be fed into an indexing machine that presses the layers together for coupling the layers together (e.g., by ultrasonic welding, laser welding, pressure sensitive adhesive, heat bonding, heat sealing, heat-activated bonding, or a combination thereof) thereby assembling the cartridge 12.

The cartridge 12 further includes a first sample collection pad 16 and a second sample collection pad 18. The first sample collection pad opening 506 is shaped and dimensioned to accommodate the first sample collection pad 16 and the second sample collection pad opening 508 is shaped and dimensioned to accommodate the second sample collection pad 18. As depicted in FIGS. 17 and 18 , the first sample collection pad 16 is positioned vertically above, but does not completely cover, the first vacuum via 410 and is positioned vertically above the first sample via 414. Similarly, the second sample collection pad 18 is positioned vertically above, but does not completely cover, the second vacuum via 412 and is positioned vertically above the second sample via 416. In some embodiments, the

specimen collection pads

16 and 18 may be a CF12 collection pad or cellulose paper. A CF12 collection pad includes a dried blood spot filter paper that can be used as a specimen collection pad. Other types of collection pads may also be employed in various aspects of the present teachings. In other embodiments, the collection pads can be in direct contact with each other.

The cartridge 12 also includes a clear adhesive seal 20 that covers the first sample collection pad 16 and the second sample collection pad 18 and allows a user to view the first sample collection pad 16 and the second sample collection pad 18. The seal 20 is affixed to the top surface 502 of the top layer 500 such that the seal 20 seals the first sample collection pad 16 and the second sample collection pad 18 between the seal 20 and the middle layer 400. The seal 20 includes a pull tab which allows a user to peel the seal 20 off of the top layer 500 along with the first sample collection pad 16 and the second sample collection pad 18. The cartridge 12 further includes a foil layer 22 that is affixed to the top of the seal 20. The foil layer 22 includes two openings that create a viewing aperture for the first and second

sample collection pads

16 and 18 respectively.

Referring now to FIG. 20 , the vacuum pin 600 is shown in accordance with an exemplary embodiment. In this embodiment, the vacuum pin 600 includes a handle 602 and a neck 604 that extends from the handle 602. The vacuum pin 600 also includes a plurality of ridges 606 that extend vertically from the neck 604. In some embodiments, the ridges 606 may be formed of an elastomeric material. When the vacuum pin 600 is disposed within the vacuum pin receptacle the ridges 606 contact a surface of the vacuum pin receptacle (e.g., a surface of the groove 518) thereby providing an airtight seal between the vacuum pin 600 and the vacuum pin receptacle.

As depicted in FIGS. 21-23 , the lancet 100 is moveable between a first position (also referred to as an “undeployed position”) (FIG. 21 ), a second position (also referred to as a “deployed position”) (FIG. 22 ), and a third position (also referred to as a “retracted position”) (FIG. 23 ).

In the undeployed position (before the lancet 100 is pushed into the cartridge 12; FIG. 21 ) the injection spring 112 and the retraction spring 114 are in a compressed state. In the compressed state, the retraction spring 114 extends vertically between the bottom wall 138 and a proximal end of the locking members 146. More specifically, a distal end of the retraction spring 114 contacts a lower surface of the proximal end of the locking members 146 and a proximal end of the retraction spring 114 contacts the inner surface 138 b of the bottom wall 138.

When in the undeployed position the outer surface 144 c contacts the inner surface 126 a of the columns 126 which compresses the side wall 136 inwardly. Furthermore, the bottom surface 154 a of the second cylinder 154 contacts and rests upon the top surfaces 144 a of the ledges 144 such that the ledges 144 supports the needle frame 108 in the undeployed position. In this position, the injection spring 112 is prevented from decompressing (due to the second cylinder 154 resting upon the ledges 144) and the needle(s) 110 is disposed completely within the inner volume 140 of the inner sleeve 106.

When the lancet 100 is inserted into the cartridge 12, the engagement of the lancet with the cartridge 12 causes the lancet 100 to automatically move from the undeployed position to the deployed position.

When the lancet 100 is pushed into the cartridge 12 (FIGS. 24-26 ), the circular extension 512 extends through the aperture 128 to contact the bottom wall 138. Specifically, a top surface of the circular extension 512 contacts the outer surface 138 a of the bottom wall 138 which forces the inner sleeve 106 to move vertically upward in the direction of arrow A (FIG. 22 ) within the housing 102. This vertical movement causes the ledges 144 to extend vertically above the top surfaces 126 b of the columns 126. Moving beyond the top surfaces 126 b of the columns 126 allows the side wall 136 to decompress and expand in the direction of arrow B (FIG. 22 ) and extend toward the inner surface 116 b of the side wall 116. In this position, the bottom surface 144 b of the ledges 144 rest upon the top surfaces 126 b of the columns 126 and the outer surfaces 144 c of the ledges 144 contacts the inner surface 116 b of the side wall 116.

The expansion of the side wall 136 causes the inner volume 140 of the inner sleeve 106 to have a larger width relative to when the inner sleeve 106 is in the undeployed position such that at least a portion of the side wall 136 has a larger width than the second cylinder 154 (the widest portion of the needle frame 108 which allows the needle frame 108 move vertically downward in the direction of arrow C) (FIG. 22 ).

Furthermore, the injection spring 112 also causes the needle frame 108 to move in the direction of arrow C as the ledges 144 no longer prevent the injection spring 112 from expanding. The force applied by the injection spring 112 causes the needle frame 108 (and therefore the needle(s) 110) to travel with a force that is sufficient to cause the needle(s) 110 to puncture the skin of a subject wearing the cartridge 12. Stated another way, the injection spring 112 causes the needle(s) 110 to extend through the aperture 150 of the inner sleeve 106, through the aperture 128 of the housing 102, and through the needle aperture 510 and the sample well of the cartridge 12 to puncture the skin of a subject. In the deployed position, the bottom surface 154 a of the second cylinder 154 rests upon the columns 142 and at least a portion of the outer surface 154 b of the second cylinder 154 contacts the inner surface 136 b of the side wall 136.

While moving in the direction of arrow C, the outer surface 152 b contacts the locking members 146 which causes a proximal portion of locking members 146 that is aligned with an opening 148 to extend into the opening. In this position, the locking members 146 no longer contact the retraction spring 114 thereby allowing the retraction spring 114 to decompress and expand. When decompressed, the retraction spring 114 contacts the outer surface 152 b of the first cylinder 152 which causes needle frame 108 to also move in the direction of arrow D (FIG. 12 ). That is, after moving to the deployed position, the retraction spring 114 causes the needle(s) 110 to retract back into the inner volume 140 of the inner sleeve 106 via the

apertures

128 and 150 of the lancet 100. After penetrating the skin of a subject, the retraction spring 114 causes the needle(s) 110 to automatically retract back into the housing of the lancet 100 thereby placing the lancet 100 in the retraced position.

As previously discussed herein, the lancet includes a mechanism that can transition the lancet between a locked state and a released state. In various embodiments, this mechanism includes the columns 126, the ledges 144, and the locking members 146. An upper locking portion of the mechanism refers to the columns 126 and the ledges 144 while a lower locking portion refers to the locking members 146 as the columns 126 and the ledges 144 can be positioned vertically above the locking members 146. The term upper interference portion refers to the top surface 144 a of the ledges 144 as this surface interferes with the needle frame's 108 ability to transition to the deployed position when the mechanism is in the locked state. As used herein, a lower interference member refers to the columns 142 as the columns 142 interfere with the needle frame's 108 ability to further extend beyond a desired position.

In use, after affixing the cartridge 12 to the skin of the subject, a user of the dermal patch system 10 pushes the lancet into the cartridge 12 which causes the needle(s) 110 to move to the deployed position and puncture the subject's skin and draw a physiological sample. After the needle(s) 110 retracts into the lancet 100, the drawn physiological sample pools within the physiological sample well of the cartridge 12.

When the physiological sample is within the physiological sample well, a user can pull the vacuum pin 600 in the direction of arrow E (FIG. 26 ) to move the vacuum pin 600 from a first position (also referred to as an “undeployed” position) (FIGS. 24 and 25 ) to a second position (FIG. 26 ) (also referred to as an “deployed” position). Moving the vacuum pin 600 to the deployed position creates a vacuum within the first vacuum pathway, the second vacuum pathway, the second sample pathway, and the second vacuum pathway. The strength of the vacuum is proportional to the amount the vacuum pin 600 moves. That is, the more the vacuum pin 600 moves, the stronger the vacuum. This vacuum causes the drawn physiological sample to travel to the first collection pad 16 and the second collection pad 18 via the first and second sample pathway respectively (FIGS. 17 and 18 ). In some embodiments, capillary flow, wicking and gravity assist the vacuum pin 600 in drawing the physiological sample towards the

collection pads

16 and 18. The first collection pad 16 and the second collection pad 18 absorb the drawn physiological sample. The user can determine the

collection pads

16 and 18 have absorbed the physiological sample by viewing the

collection pads

16 and 18 through the transparent adhesive seal 20.

After the

collection pads

16 and 18 have absorbed the physiological sample, the user can remove the cartridge 12 from the subject's skin. The user can then send the cartridge 12 to a laboratory where a medical professional can remove the

collection pads

16 and 18 by pulling the pull tab of the seal 20. Once removed, the medical professional can apply various solutions to the

collection pads

16 and 18 which mixes with the physiological sample to form a processed physiological sample that has been freed from the

collection pads

16 and 18.

With reference to FIG. 27 , in some embodiments wherein the cartridge 12 includes the QR code 26, a user of a computer system 28 may scan the QR code 26 to determine a test to perform on the stored physiological sample and/or to view and/or update an EMR 30 that is associated with the QR code 26. In these embodiments, the EMR 30 is stored in an EMR database 32 that is in communication with the computer system 28. Furthermore, the QR code 26 may be employed to preserve the chain of custody of the dermal patch system 10.

In these embodiments, the computer system 28 may include an application that provides access to the EMR database 32 via a network connection and allows a user to photograph of scan the QR code 26. As shown in FIG. 27 , the EMR database 32 includes a plurality of EMRs 30 each of which is associated with an individual subject. The application causes the computer system 28 to scan or retrieve an image of the QR code 26, analyze the QR code 26 and associate the QR code 26 with an EMR 30. In some embodiments, the computer system 28 may then update the associated EMR 30 to indicate a physiological sample has been obtained from the subject. The computer system 28 may automatically update the EMR 30 automatically or based on a user input. In some embodiments, after associating an EMR 30 with the QR code 26, the computer system 28 may analyze information within the EMR 30 to determine a test to be performed on the obtained physiological sample and may prompt a user of the computer system to perform the test.
